Question about CDs

[Joy]

This probably isn't the "proper" NewsGroup to ask this, if not, can someone
steer me in the right direction? A friend said she put some pictures on a
CD-R and wants to add more. Can it be done with that? She said she also
has some CD (without the R) and she understands you can NOT add more to
those? We are not sure of the differences, and would appreciate any
clarification. TIA

CD-Rs are a onetime deal. Use a CD-RW disk.

Track-at-Once, Close Disc. Creates a write-protected CD. Files cannot be
added after the CD is closed.

from Nero HELP:
[[Note: If you wish to create a CD-ROM as a single session, you must click
on the Finalize CD box. Do not click this box for a session of a
multi-session CD, unless it is the last session. The CD is write-protected
after this.]]

[[CD-R stands for Compact Disc-Recordable and can be recorded only once.
You may continue to add files until the CD is full as long as the disc is
not closed (write-protected). You cannot delete, rename, rearrange, or
alter the files or file structure on the CD after recording.

CD-RW stands for Compact Disc-Rewritable. It allows you to record the disc
and then erase the entire disc and start over. You cannot select certain
files to delete; you must erase the entire disc. Unless you erase the disc,
you cannot delete, rename, rearrange, or alter the files or file structure
on the CD after recording. ]]

If you use some 3rd party CD burning software, you can treat CD-RW disks
like floppy disks, erasing and adding files at will. Depends on a number of
things. But, you cannot treat CD-RW disks like floppy disks with Windows
XP's native CD burning utility.

Open CD:
[[If a CD is open, it means that further information can be added to it. It
is not write protected.]]

Closed CD:
[[If a CD is closed, it is permanently write-protected. No further
information can be added to the disc. Closing a CD is analogous to moving
the write-protect tab on a floppy disc to the write-protect position.
However, unlike floppies, you can only change the write-protect setting on a
burned CD once. Once the disc is write-protected (closed), this setting is
permanent.]]

Thank you very much for the prompt reply! I have forwarded this

My original question was to help a friend, but I'm wondering something for
myself. My computer came with a 3rd party CD burning software, it also has
DVD playing/burning capability. So, reading the website Rock sent about
Burning CDs in WinXP, what about burning DVDs? Seems I have to change some
settings in order to do that. I've used both CDs and DVDs to back up data
periodically, but lately I've had problems with either/both, so I must
confess I haven't backed up lately (which is not good!) Any
help/suggestions will be appreciated. Thanks.

XP's CD burning wizard will NOT burn DVDs period.

<quote>
This burning method is strictly for CD media only. There is no support at
all in the inbuilt burning for burning DVD media.

You need to use your 3rd party software to burn DVDs.

BTW, DVDs hold way more than CDs can.

What program are you using for backup?

More can be added if the session is left open, and there's ample space in
the TOC and remaining part of the CD for file data.

Cdrw has the advantage of being able to reuse the media, cdr cannot be
reused once filled. A closed session is considered filled in this case.

Commercially written CDs can never been written to, they are pressed not
burned.

 

[Joy]

It came with Drag'n Drop Software, but the last couple of times I tried to
use it, it seemed to not want to work the way it originally did. (Like it
would say the disk was full when it was a brand new one). I called Toshiba
for help and it seems there is some place I have to click on something
(descriptive, huh?) to make it do DVDs rather than CDs. I have a computer
man coming to the house, hopefully tomorrow, to help me figure it out. I
also (some time back) bought an external hard drive (with Ghost software) so
I could back up EVERYTHING, not just data. I thought I did so a couple of
months ago, but I cannot seem to figure out how to use that either, so I
plan to have the computer man help with that also. (I'm really not this
dumb when it comes to other aspects of computers! In fact I often help
OTHER people!)

Is this why commercial cds are higher quality than burned cds?

Commerically pressed CDs don't have the same material requirements as
burnable and re-burnable CDs. I wouldn't say one is better than another. I
have one inop MS operating system (98) installation CD, and one MS made (Age
of Empires II - The Conquerors) installation game CD. Both were kept in the
hard covers, not paper sleeves. No fingers touched the reading surface.
Guessing was a bad batch material. CDRs and CDRWs also have batch problems
as well.

Thanks for your comments, Johnny. I appreciate them.
